In winter, concrete faces two main challenges, one is retardation, and the other is concrete frost heave: When retardation occurs, the strength of concrete is not increased and it is easy to be frosted which causing the project to be seriously delayed. Frost heave mostly occurs in the early spring, the strength, impermeability, and durability of concrete are reduced, and the quality of the project will also be greatly reduced. So how can we prevent this situation? We need to provide temperature support for the raw materials to help the concrete preparation project not be affected by low temperature. Thus, in this article, we will discuss how to operate concrete batching plant in winter.

Operating Concrete Batching Plant in Winter

First of all, we have to select suitable raw material. In order to reach the initial setting time as soon as possible, we choose early-strength cement to improve early strength and reduce frost damage. In the selection of sand and gravel, we should pay attention to the use of sand and gravel with reduced water content such raw materials have less water content and reduce frost damage. The water content should be controlled below 4%. In winter, there is a lot of rain and snow. We recommend that you make preparations in advance when building a concrete mixing plant. You can build an aggregate silo or cover it with gauze.

Secondly, what we have to consider is the temperature control of the equipment. The small concrete batching plant has good economic efficiency in terms of investment cost, but once it comes to bad weather, such as rain, snow, strong wind, thunder and lightning, etc., the production may be delayed due to the simple equipment. It is very normal that such a mixing station cannot operate normally in winter. Instead of thinking about how to configure the stove, electric heating, and security devices at this time, it is better to plan ahead and consider all abnormal conditions when purchasing. It is better to plant ahead and considers all abnormal conditions when purchasing.

Thirdly, in order to ensure the normal operation of the equipment, the concrete batching plant with low temperature resistance should be closed to the collection bin, admixture tank, mixer, etc. One is to prevent dust and noise, and the second is to keep warm. After sealing, electric heater can be placed to guarantee the temperature. If conditions permit, it can also be heated by several kinds of boilers, and the heating pipeline can be passed through the main equipment of the mixing plant. At present, many concrete mixing plants in China have made great progress in providing interfaces for antifreeze and airtight facilities for thermal insulation. In severe winter areas such as Russia, the normal operation of the equipment can still be ensured.
